The point where things break seems to be loading the aha1542 driver as a
module.

Steps to reproduce the problem:
- Compile a kernel with scsi.
- Load aha1542 and sr_mod.
- Mount a CD-ROM.
-> SCSI DMA out-of-memory, disabling scatter-gather, ...

- Compile a kernel with scsi and aha1242.
- Load sr_mod.
- Mount the same CD-ROM.
-> No problem at all.

Right now I don't know where to look further. :-/
